STRUCTURE AND FUNCTION
The hoist is an electro-hydraulic 4 post surface-mounted hoist.
The hoist consists of 2 pairs of posts connected with cross beams. The 2 platforms rest on the cross
beams.
Platforms and cross beams are raised and lowered by means of cables and a hydraulic cylinder
placed under one platform. The cables are attached to a yoke on the piston rod and run via cable
pulleys to the four post tops with an incorporated adjustment device.
The hydraulic pump unit and control box are placed on the rear right post.
The hoist is operated by means of pushbuttons showing the UP, DOWN and LOCK functions with
indicators. The pushbuttons are placed on the control box - see illustration below.
